Korean golfer D.H. Lee was sitting in the top-10 at the AT&T National at Congressional Country Club in Potomac, MD.

But Saturday turned out to be his worst round of the tournament thus far, as he shot a 75 to finish 4-over for the day and is now just 1-under for the tournament (six shots behind the leaders) and tied for twentieth place.

During his round he let frustration get the best of him, flipping off the gallery. It's unknown why he made this gesture. Perhaps he was not happy with his recent shot, or perhaps he was upset with something a fan did during his back swing. WARNING: In both images, you can distinctly see Lee flipping the middle finger.

That tournament has been marred by torrent rainstorms and the fact that Tiger Woods, who hosts the tournament is not participating because of an elbow injury.
